1. INTRODUCTION

DFR series are designed to measure liquid level
by using buoyancy and magnetic force as
multi-wire signal transmission.

2. FEATURES

- Widely available with narrow space in complicated environment.

(semiconductor manufacturing equipment, steam sauna,
medical equipment,vending machine, air conditional and
solar thermal plant ... etc.)

- Accurate contact output.
- Customizing in your flavor.

3. OPERATION PRINCIPLE

While float moves up / down as liquid level rises / falls,
the magnetic force within the float will operate the reed switch(stem)

so that the resistance value(measurement) varies.
